`seription of the invention7 such `as-will enable others skilled inthefzart whichI .it appertains to make and' use the same.

The object of the invention is to provide simple and eiiicient means formaintaining a table top in a condition of horizontality regardless ofvibrationsl and oscillations of the support or base of the same, andmore especially to provide a table which is adapted for use onship-board, wherein the top is maintained in a proper position to holdand sustain the objects imposed thereon regardless of the rolling orpitching of the vessel, and in connection with the .gravita-y tionalleveling means provided for the table to employ means serving to preventa pendulous or prolonged swinging movement ot the table top; and withthis object lin view the invention consists in a construction andcombination of parts of which a preferred embodiment is shown in thedrawings, wherein:

Figure 1 is a. side view partly in section of a table embodying theinvention.

Figure 2 is a horizontal section on the plane indicated by the line 2-2of Figure 1.

Figure 3 is a detail view of the ring forming one element ot' theuniversal mounting7 Figure 4 is a detail section of a port-ion of one ofthe equalizing devices.

Figures 5 and 6 are elevations from different sides of a modifiedconstruction of the table.

1n the construction illustrated in Figures 1 to i inclusive the tabletop 10 is carried by a weighted stem 11 which is universally mountedupon a frame including the supporting disk 12 and the legs or standards13 .which may be transversely connected by a suitable brace 14. The stem11 is provided at its lower end with a weight 15 of suficient weight toinsure stability and avoid vibration except under conditions involvingunusual movement of the supporting vessel, said stein having a ball 16provided with trunnions 17 which are mounted in seats 18 in a ring 19which in turn is provided with trunnions 20 disposed in a plane at rightangle, to thatofthestrunnions:18yandlare mounted .in bearings fin thedisk` y12,**fto"the end 'that the weight 15 is adapted to tain thestem'11 in vatrulyv vertical position and.,hen'cefft'he table "top 10 'inlahorizont-al position regardless of movementyofthesup#v ppr-,ng frameVconsisting fdisk` fand y .i

` The weight is secured upon the stem'11 `hy means of a nut 22 or theequivalent thereof, and the attaching plate 23 at the upper end of thestem is preferably integral therewith andis secured by` screws 2litojthe under surface of the table top.

Disposed at intervals inv a series concentric,

withthe stem 11 vor the axial center ot' the supporting :trame are theequalizing devices consisting in the construction shown in Fig-` ures 1and l ot cylinders or dash pots 25 in' which operate pistons 26 of whichthe rods*` 27 are pivotaliy connected as at 28 to the under surtace ofthe table top, the lower ends oi' the cylinders or dash pots beinguniversally mounted as by ball and socket joints 29 upon the legs orstandards .of the trame work and being provided with vents 30 fittedwith regulating valves 31 to modify the freedom of the passage of airvthrough the vents due to the downward and upward movement of thepistons incidental to the movement of the supporting traine withrelation to the horizontallymaintained table top 10. These equalizingmeans ot' which a plurality should be provided with each apparatus, tendto relieve the jars incident to the sudden movements of the support-ingtraine with relation to the table top and permit the latter to bemaintained in a substantially uniform horizontal position `without thevibration or swinging movement which would be incl'- ,dental otherwiseto the impulses imparted to 1n the modied construction iilustrated'inFigures 5 and 6 the table top 32 is attached also having acounter-balancing weight 34;

'and a ball 36 which ismounted in a spherical socket 37 supported by orforming a part or the disk 38 upheld by the legs or standards 39 whichare braced lasl indicated at 40. The stem with itsbearing ball and to aplate atthe upper end of a stem 34 attaching plate 33 is preferably ofsingle piece construction, as in the form illustrated in Figure l, andthe equalizing devices emk ployed in connection With the form shown inFigures and 6 consists of bars 4:1 sup` ported by cushioning springs i2and traversed by Wings 43 depending from the table top and having apivotal or rocking mounting thereon as shown at 44, the intermediateportions of said Wings forming run ners 45 having a tongue and grooveengagement With the bars l so as to compensate for the angular relativemovement in any direction of the table top and supporting frame andserve to prevent the swinging or prolonged vibratory movement of thetable top due to the :movement of the surface by which the frame of thestructure is supported.

from the axis thereof and to said legs at a distance above the bases ofsaid legs, and said supports being disposed respectively in planespassing intermediate the terminals of the legs supporting them.
